CO2 Level Hits Record High

The Scripps Institute of Oceanography at UC San Diego takes daily measurements of the atmospheric CO2 levels on Maua Loa, HI. This is the oldest continuous measurement of atmospheric CO2 and is known as the Keeling Curve after the Charles David Keeling who started the measurements back in the 1950s. On March 15, it measured the CO2 level to be 403.10 parts per million (ppm). This is the highest level ever recorded at Mauna Loa. But, don't worry too much, this record will be broken many times this year.
